Kiln Drying
Kiln Drying (Hardwood Flooring)
Floor Detective® Claims and Conditions Guide
Summary
Kiln drying is a controlled manufacturing process used to reduce the moisture content of hardwood lumber before flooring production. Temperature, airflow, and humidity are regulated to gradually remove moisture while limiting internal drying stress within the wood structure. Proper kiln drying helps improve dimensional stability, machining consistency, and long-term performance, but it does not eliminate future movement after installation because wood continues to respond to environmental humidity throughout its service life. Uneven or aggressive drying may contribute to internal stress characteristics such as checking, honeycombing, or casehardening, although later in-service movement alone does not independently establish kiln-drying deficiency without correlation to manufacturing-origin stress patterns. Solid and engineered flooring systems may respond differently to drying-related stress because of differences in construction, veneer/core interaction, and layered stability.
